2025 has already shaped up to be another record-breaking year for Rotech Subsea as demand for its controlled flow excavation (CFE) solutions continues to rise across the global energy sector. Building on the momentum of its 30th anniversary celebrations in 2024, the Aberdeen-based business has experienced significant growth over the past two years, with revenue on track to have increased by 90% since 2023.
A contributing factor to this growth has been Rotech’s sustained activity in the Asian offshore wind market. With 7 projects completed to date and several still ongoing, Rotech has completed a variety of scopes across the entire project lifecycle for both global and regional contractors.
In March, Rotech’s equipment quite literally reached new heights when a Boeing 747F was chartered to transport an RS spread directly to Taipei at the request of a major client. Despite alternative solutions being readily available in-country, the client specifically requested Rotech’s proven systems and experienced team to lead the project, a testament to the trust and confidence Rotech’s client base has for its proven reliability and results. From the runway to demobilisation, the project was successfully completed in under 2 weeks.
Prolonged demand in the region has resulted in the promotion of Alasdair Maclean to Country Manager, who has relocated to Taichung to provide a dedicated in-country presence. With no signs of slowing down, the business is continuing to recruit additional onshore personnel to further bolster its in-country team.
Speaking on the demand experienced, Maclean said “We started the year with three RS spreads of equipment supporting client scopes in the region. However with demand continuing to grow, we have since mobilised a fourth spread as well as one of our RSG-C grab-cutters to meet the workload.”
Looking ahead, Stephen Cochrane, Director of Subsea and Global Head of Business Development, believes the company’s achievements in Taiwan are laying the groundwork for broader expansion across the APAC region. “The strength of our operations in Taiwan will support our continued growth into the Australian market, particularly as it moves deeper into the decommissioning phase,” he explained. “Our technology and experience are ideally suited to meet those emerging needs.”
Beyond Asia, Rotech Subsea continues to maintain a strong presence in North America despite challenging market conditions. While the US offshore wind sector faces political and regulatory headwinds, demand for Rotech’s solutions has remained constant. This demand spans from required maintenance scopes for already established wind farms, to supporting the continued development of offshore power networks. To meet this demand, a second spread has now been sent to the region, demonstrating the versatility of both the company’s equipment and its team to support a range of end markets.
At its Aberdeen headquarters, Director of Base Operations Martin Graham described the company’s momentum as strong and sustained. “Normally demand eases off at the tail end of summer, but right now every Rotech spread is booked and busy. The yard looks quite empty because our fleet is out supporting key client scopes worldwide.”
Biding by its mantra ‘Design, Build, Operate’, Rotech is continuing to add to its equipment fleet, which already consists of 32 systems. This will soon increase to 36 as the business builds additional RS2 and RS3 tools to keep up with global demand from its customers. Summing up this customer-centric approach, Managing Director Dr Donald Stewart said “At every stage of the process, Rotech will go out of their way to make sure the client gets the results they are looking for.”
As Rotech begins to look towards 2026, demand across the energy sector remains constant, proven by a solid pipeline of secured work and opportunities. With its growing international team, equipment fleet and proven track record, Rotech continues to build the foundations for continued international growth.
